PHP/MySQL and React/Redux. We also used Electron for the front-end desktop software. Electron certainly comes with a ton of baggage but upon evaluating all other options, we decided to go with it because it was the best fit for our team´s experience. Other than that, there were actually very few tech pieces involved. I am an extreme minimalist by nature so I kept things as simple as possible in order to minimize the surface and complexity of the code base. Overall, it took us 9 Months in total to build the application from a prototype phase to a full blown trading system. We did it so fast because we kept things simple and low in complexity.
